 terreus (designated At_cad) into this yeast and established the initial titer of IA at 135 ​± ​5 ​mg/L. Subsequent overexpression of a native mitochondrial tricarboxylate transporter (herein designated Pk_mttA) presumably delivered cis-aconitate efficiently to the cytosol and doubled the IA production. By introducing the newly invented CRISPR-Cas9 system into P. kudriavzevii, we successfully knocked out both copies of the gene encoding isocitrate dehydrogenase (ICD), aiming to increase the availability of cis-aconitate. The resulting P. kudriavzevii strain, devoid of ICD and overexpressing Pk_mttA and At_cad on its genome produced IA at 505 ​± ​17.7 ​mg/L in shake flasks, and 1232 ​± ​64 ​mg/L in fed-batch fermentation. Because the usage of an acid-tolerant species does not require pH adjustment during fermentation, this work demonstrates the great potential of engineering P. kudriavzevii as an industrial chassis for the production of organic acid.

Rainfall can have immediate effects on parasitism rates by affecting parasite survival and movement in the environment, or it can have delayed effects by affecting host susceptibility to parasites through changes in host body condition or immune function. In this study, we examined how helminth infection in a wild ungulate (Grant's gazelle, Nanger granti) is impacted by seasonal changes in rainfall. We looked at how the burdens of three helminth parasites varied in relation to current (immediate effect) and prior (delayed effect) rainfall by comparing parasite fecal egg and larval counts to rainfall 0, 1, and 2 months prior to parasite sampling. We found burdens of all three parasites to be negatively associated with rainfall, and that delayed effects were stronger than immediate effects. Our findings implicate rainfall as a driver of seasonal variation in infection and suggest one important mechanism may be through delayed effects on host susceptibility. © 2020 The Author(s).In this retrospective cohort study, oral glucose tolerance testing (OGTT) was performed for all enrolled survivors of patients who suffered from acute lymphoblastic leukemia (ALL) at least 9 months after ending chemotherapy, as well as for control group. All demographic, treatment and anthropomorphic data were obtained from medical records. Furthermore, insulin resistance was evaluated according to insulin level, Matsuda and HOMA-IR index. Of 53 subjects, 28 exhibited B-cell ALL, and 25 were healthy children (F/M = 1.12/1). Mean age (±SD) was determined to be 10.77 ± 2.83 years, and meantime off for therapy was also recorded as 3.0 ± 1.6 years. ALL patients were diagnosed at age 1-15 years; none of them received the cranial radiotherapy, and demographic characteristics (age, sex, and sexual maturity) were found to be the same in both groups. Seven patients showed transient hyperglycemia during ALL treatment, however, no significant differences were found in terms of body mass index (BMI) means between ALL patients with and without transient hyperglycemia. Based on the data presented herein, insulin resistance could not be predicted by glucose levels during therapy, cumulative asparaginase, and steroid. Our findings demonstrated that elevated BMI could be a valuable predictor of insulin resistance probability in ALL patients. The presence of transient hyperglycemia does not appear to be associated with the increased risk of glucose intolerance or insulin resistance in the first few years after completion of therapy. © 2020 The Author(s).A 69-year-old man had experienced right chest pain for several months. Chest computed tomography (CT) showed a right upper lobe lung tumor and swelling of multiple mediastinal and right hilar lymph node. Three punctures to 4R lymph nodes and two punctures to 11i lymph nodes were performed, using endobronchial ultrasonography. Thirty days after punctures, he was admitted with appetite loss and general fatigue. Chest CT supposed the evidence of mediastinitis and pericarditis. Despite the antibiotics, cardiac tamponade developed on the third hospital day. Pericardial fenestration and pericardial drainage were performed. Gram-positive cocci were identified and Gemella sanguinis was eventually identified as the microbial identification system. Like the former reports, the necessity of surgical procedure for late onset of mediastinitis and pericarditis. caused by EBUS-TBNA was suggested. © 2020 Published by Elsevier Ltd.Background Bronchopleural fistulas (BPF) are abnormal sinus tracts connecting the bronchi and pleural cavity and form after surgical resection of a lung lobe. It is a complication with potentially disastrous sequelae including, failure of the bronchial stump to heal, ischemia of the affected area, and/or infection of the stump. Bronchopleural fistulas caused by surgical intervention most commonly present on the right side and within 7-12 days post-operatively, i.e., subacutely. While the fistula may initially be asymptomatic, they carry a mortality rate of 25-71% in the absence of other comorbidities. Case presentation A 60-year-old female developed a BPF more than seven months after a left lower lobe lung lobectomy for non-small cell adenocarcinoma is presented. She was seen at our hospital on multiple occasions after her lobectomy with no evidence of a developing fistula on chest computer tomography (CT) during those visits. During her most recent presentation, roughly 7 months postoperatively, she was noted on imaging to have a new left-sided bronchopleural fistula. Bronchoscopy with lavage and culture of the fistula grew Pseudomonas Aeruginosa, for which she received appropriate treatment. Further surgical interventions were deferred due to poor prognosis. Her presentation differed from the typical BPF presentation in that it was left-sided and occurred out of the window of its usual occurrence. Conclusion Late-onset BPF is an important diagnosis to consider in patients who have undergone lung resection, regardless of the type of surgery or postoperative duration, especially when patients are known to have multiple predisposing factors. © 2020 Published by Elsevier Ltd.
